IMPROVEMENT IN GORNWLANIRS.

Specification forming part of Letterey Patent No. 14855312, dated March17, 1874; application filed February 7, 1874.

CASE A.

To all whom fit may concern:

Be it known that I, GEORGE W. BitowN, of Galesburg, county of Knox andState of Illinois, have invented certain new and useful Improvements inMachines for Planting Corn, of which the following is a speciiication:

The present invention relates to that class of corn-planters in which atubular case is arranged, through which the seed, in measured portions,is conveyed from the seed-box to the furrow opened for its reception 5and it consists in constructing the valve for intercepting the seed,near the lower end of the seed-tube, with wings for detlecting thedescending charges alternately to dual inclines, upon which it isreceived and retained by said valve until discharged within view of thedriver from his seat upon the machine, all as herein after fullydescribed.

To enable those skilled in the art to understand and use my invention, Iwill now proceed to describe the manner in which the same is or may becarried into effect by reference to the accompanying drawing, in whichthe similar letters used as marks of reference apply to the like partsin all of the figures.

Figure l is an elevation of the rear side of a seed-tube, and theadjacent parts of a seedbox or hopper, and the lower ends of a portionof the devices constituting my invention. Fig. 2 is the same view, withthe rear sides of the seed-tube and hopper removed, and exhibits a fullrear elevation of the invention. Fig. 3 is a perspective view of thesame parts, as shown at Fig. 2, except the right-hand side of theseed-tube is broken away. et isan elevation of the left-hand side ofFig. 1, with the front side of the seed-tube removed. Fig. 5 is aperspective view of the vibrating valve and two sides of the seed-tube,seen from the front. Figs. 6 and 7 are detail views.

Referring to the parts by letters, letter A represents a portion of aseed-box or hopper, and B a detached portion of the reciprocating bar,which, in ordinary machines, transmits motion to the devices formeasuring the ch arges' motion to the vibrating valve, which interceptsand collects the seed composing each separate charge near the lower endof the seed-tube, for the purpose of depositing, without dribbling, inthe furrow formed by any suitable furrowopener. The vibrating valve, orilipper,77

heretofore used in machines of this class, hasV functions were such asto require very light construction. My improvement in this direc-- tionconsists in constructing the vibrating.

valve, as shown by letter D in the drawing, with an upper stem end,@which receives the impulse to operate it from the bar B, and isenlarged laterally nea-r its lower end to very nearly the width of theopening or duct in the seed-tube, (see Fig. 2,) at which point it ispivoted at d in said tube, and thence tapered to its lower end in suchmanner that when at the limit of its throw in either direction, itstapered side -nearest the side of the tube will be parallel therewith. DD are wings, extending at right angles from one side of the valve D, andtheir sides parallel with the tapered sides thereof, their upperendsopposite the pivot-point d', and their lower ends terminated so asto leave a projecting lower end or tongue, d, of the valve l), as shownplainly in the drawings. E is the valve-seat, and is formed as shownmore plainly at Figs. 6 and 7 ,which are .perspective and side viewsthereof, respectively. It is iitted snugly against the front wall of theseed-tube, its central upper portion e extending baclr to the samevertical plane as the adjacent side of the tongue f, thence downward ashort distance in the same plane, its upper surface on each side of theprojection c cut into inclined groovesc el., the terminating forwardends of which are in the same vertical plane as the outer end ofprojection e, and together therewith form faces borne upon by the tongued in its vibrations. rlhe block E is located in the seed-tube with itslower or discharging end below the plane of the lower end of the rearwall of said tube,

and its upper end situated relatively to the valve D, so that iu thevibrations of said valve upon its axis of oscillation d', the lower endsof the wings D D will alternately be brought into juxtaposition with thecentral projection c. The seed, in quantities as desired for each hill,isv nieasured and separatedl from the inass of seed in the box A by anysuitable mechanism, operated also, generally, by the saine motiveapparatus which propels the vibrating valve D, and in such manner that acharge of seed is delivered from the seed-box, and7 passing downwardwithin the seed-tube, is received between the wings D D at each forwardand return stroke of the valve D, the wings D D acting as deliectors tocarry said charges of seed alternately to the incline grooves c e, atthe lower ends of which it is retained by the tongue d, until saidtongue is carried, by a return move of the valve D, to the opposite sideofthe tube C, when the charge of seed will drop to the furrow preparedfor its reception, in view of the operator, who may thus know whenv thedroppin devices are operating, and avoid the possibility of passingalong without planting.

Having now described the manner in which my invention :may be carriedinto effect7 what I desire to secure by Letters Patentis- The vibratingseed-valve D, having wings D D', arranged to operate with the fixediuclines c e, substantially as and for the purpose specified.
